Subject: [PATCH 3/4] b43: HT-PHY: init: copy tables and reset CCA
Date: Fri, 12 Aug 2011 13:13:46 +0200 [thread overview]

Copying comes from following part of the dump:
phy_write(0x0072) <- 0x1d44
phy_read(0x0073) -> 0x0002
phy_write(0x0072) <- 0x1d4a
phy_write(0x0073) <- 0x0002
phy_write(0x0072) <- 0x1d54
phy_read(0x0073) -> 0x0002
phy_write(0x0072) <- 0x1d5a
phy_write(0x0073) <- 0x0002
phy_write(0x0072) <- 0x1d64
phy_read(0x0073) -> 0x0002
phy_write(0x0072) <- 0x1d6a
phy_write(0x0073) <- 0x0002
CCA reset from dump (known from N-PHY):
read32 0xb0601408 -> 0x00002055
write32 0xb0601408 <- 0x00002057
read32 0xb0601408 -> 0x00002057
phy_read(0x0001) -> 0x0000
phy_write(0x0001) <- 0x4000
phy_write(0x0001) <- 0x0000
read32 0xb0601408 -> 0x00002057
write32 0xb0601408 <- 0x00002055
read32 0xb0601408 -> 0x00002055
Finally well-known MAC PHY clock en:
read32 0xb0601408 -> 0x00002055
write32 0xb0601408 <- 0x00002055
read32 0xb0601408 -> 0x00002055
